Research Question & Hypotheses

Describe your study in plain language. The AI uses this — together with your dataset profile and variable definitions — to build a complete analysis plan.

What is your research question?

Does the active intervention (Group B) improve 90-day survival compared to standard care, adjusting for age, sex, baseline clinical status, comorbidity burden, and enrollment site?

Hypothesis

State what you expect to find. If you have a clear expectation about the direction of the effect (e.g., Group B will outperform Group A), be explicit about it.

Group B improves 90-day survival over standard care (Group A).

Any suspected interactions? (optional)

Describe in plain language if you think any variable's effect depends on another. The AI will translate this into an interaction term in the model formula.

I suspect the treatment benefit may differ depending on how unwell patients were at baseline — sicker patients at entry might respond differently to the intervention.
